The article summarises and brings together the results of isotopic studies of the population of Great Moravia, mainly of the inhabitants of the Mikulcice agglomeration, focused on the reconstruction of diet, migration, but also methods of farming in the studied area. The work interprets as yet unpublished data on the diet of individuals buried inside the Mikulcice churches (n = 10) and on the residential mobility of individuals from Mikulcice with specific grave goods (n = 33).
It also presents precise quantitative models of the reconstruction of the diet of the Mikulcice population using recently published data on grains found in various parts of the Mikulcice settlement agglomeration. The final part is devoted to areas of future research.
